I have to create an object of ModelWeights
using Guice Dependency injection. How can I bind a double[][]
array using Guice dependency injection during runtime?
public class MW {
private double[][] weights;
private LogConditionalObjectiveFunction objectiveFunction;
@Inject
public MW(double[][] weights, LogConditionalObjectiveFunction func)
{
this.weights = weights;
this.objectiveFunction = func;
}
public double[][] getWeights()
{
return this.weights;
}
public LogConditionalObjectiveFunction getObjectiveFunction()
{
return this.objectiveFunction;
}
}
I got this while trying several approaches:
1) No implementation for double[][] was bound.
while locating double[][]
for parameter 0 at com.data.MW.<init>(MW.java:13)
while locating com.data.MW
for parameter 0 at com.predictor.impl.MEP.<init>(MEP.java:50)
at com.ServletDependencyInjector$1.configureServlets(ServletDependencyInjector.java:72)
Use Guice constants binding
@Inject
public ModelWeights(@Named("MyMatrix") double[][] weights, LogConditionalObjectiveFunction func) {
this.weights = weights;
this.objectiveFunction = func;
}
And in your Guice setup code
@Override
protected void configure() {
bind(double[][].class).annotatedWith(Names.named("MyMatrix")).toInstance(MY_MATRIX);
}
